A hybrid photo/video shooter needs to maintain the warming effect of a Tiffen warming soft FX filter while using auto white balance or grey card white balance, which cancels out the filter's color, and wants to avoid repeatedly screwing/unscrewing the filter.

No existing solution allows a hybrid shooter to quickly toggle or preset a color-grading effect like the warming filter while using standard white balance methods, without physically swapping filters or risking inconsistent results with WB shift.

Workarounds Described

manually screwing on/off the warming filter to lock WB before adding filter
using WB shift which may deliver wonky results

Implied Software Gaps

App-controlled white balance offset that automatically compensates for the filter's color effect without manual trial and error

App Concept

FilterStack Pro

A magnetic filter stacking system with preset calibration profiles. The warming filter attaches magnetically to the VND, and a companion app remembers the exact WB shift needed to preserve the warming effect. With a quick smartphone tap or camera button, the user applies the shift, letting them use auto WB normally and toggle the filter effect on/off without losing the warmth.

Key Features

Magnetic quick-attach filter holder for stacking warming filters on VND
App-based WB shift calibration: measure base WB, add filter, and store the exact offset
One-tap toggle to apply or remove the WB shift via Bluetooth camera trigger or phone
Lightweight and compact design for hybrid shooting

Target Users: Hybrid photographers/videographers who frequently use color-effect filters with variable ND filters

Revenue Model: $49.99 for the magnetic adapter kit, with optional $2.99/month app subscription for advanced calibration profiles and presets
